Using Reinforced Vapor Barrier in Crawl Spaces

  • Just about every waterproofing company is pushing reinforced crawl space vapor barrier material.
  • Reinforced vapor barrier material can separate over time because the cord is installed by gluing two pieces of plastic together.
  • The lack of separation in vapor barrier is only as good as the glue used.
  • When the reinforcement cord is exposed and becomes wet it can give off an odor similar to cat urine.
  • Why risk a potential odor problem by using a reinforced crawl space vapor barrier material?
